Positivist or post-positivist philosophy of science? The left Vienna Circle and Thomas Kuhn

The debate between the revisionist and received views of the relationship between Thomas Kuhn and logical empiricism has until now focused on the relationship between Kuhn and Rudolf Carnap. Here, I consider the relationship between Kuhn and two other members of the Vienna Circle's left-wing; Otto Neurath and Philipp Frank. It is argued that the attribution of the historical turn in philosophy of science to Kuhn obscures the historical awareness displayed in important works by members of the Vienna Circle, and thereby distorts its legacy. Both Frank and Neurath recognised the role for history in theorizing about science, and drawing upon these insights lead them to considerations of scientific theory-choice, rational disagreement, and the role of extra-scientific values in science, that anticipate those later made famous by Kuhn. It is also argued that the Left-Vienna Circle's programme for Unified Science, the replacement of traditional philosophy with a bipartite metatheory of science, provides a clearer and potentially more radical role for the history of science within the philosophy of science than Kuhn's. To reach this conclusion, it is demonstrated that some members of the Vienna Circle maintained a far less robust distinction between contexts of discovery and justification than has typically been attributed to them.
